' ,IIVIPROVEMVENT IN MACHIVNEYS FOR ROLLING HORSESHOE-BLANKS.

Specification forming part of Letters Patent No. 168,205, datedSeptember 28, 1875 application filed March 720, 1875.

To all whom it may concern:

form of blank. v

Like letters refer to like parts Whenever they occur.

My invention relates to the construction The horseshoe-bar is fedbetween the rolls,-

and arrangement of rolls for rolling horseshoeblanks; and it consists inthe combination of two rolls, the axes of which cross each other atanangle while the faces of the rolls are parallel, and are provided withannular grooves and creasers, whereby the crease inthe blank is inclinedbackward and the weightof metal may be thrown upon the outer edge of theblank, thus giving a better hold for and facilitating the driving of thenail.

Heretofore, in the manufacture of horseshoe-blanks, where the creasershave been attached to rolls having parallel axes, the'weight orthickness of metal between the crease and toe has been on the creasedside, which resulted in the crease having an outward slant, whichprevented the nail from being properly driven in shoeing.

The object of the present invention isto correct this objectionablefeature in the rolling of the blank, which I accomplish by canting therolls; but as this of itself would destroy the parallelism of the sidesof the blank, I taper the canted roll so as to preserve the rectangularcondition of the blank.

' I will now proceed to describe my invention, so that others skilled inthe art may apply the same. r

In the drawing referred to, A represents the housings, provided with theusual boxes for journaling the shafts of the rolls B and O. B is theupper roll, tapered so as to render the face thereof parallel with theface of the lower roll, and having its shaft b set at, or

Fig. 3 is a view of a blank, the dotted line showing the old about at,an angle of ten degrees to the plane of the lower or second roll, 0.Upon the roll B, arranged at regular intervals at right angles to theaxis of the roll, are a series of creasers, 12 between each set of whichmay be placed the cutters for dividing the blanks. 0 indicates the lowerroll, having the shaft 0, the axis of which is in a horizontal plane,said roll being provided with the annular groove 0 one flange, o ofwhich is deeper than the other, and is preferably so made as to lap theedge of the tapered roll to permit the extension of the metal displacedby the creasers, so as to fill up the outsideedge of the crease. Therolls B and O are also provided with the gear-wheels b and 0 so as tomove in unison, and are driven from any suitable power.-

The operation of the devices is as follows:

and, being confined by the groove of the horizontal roll, the creasers,which are set at right angles to the axis of the canted roll, willindent the bar at such an angle as is shown in Fig. 3 of the drawing,the displaced metal extruding by the lapping flange c to fill out theedge of the crease, and the parallelism of the faces of the blank beingpreserved by the taper of the upper roll. The canting of the rollalsofacilitates the cleaning or disengaging of the creasers.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The rolls B (J, for rolling horseshoe-blanks, one provided with anannular groove, and the other provided with creasers, the axes oftherolls crossing each other while the faces of the rolls are parallel;1

2. The two rolls B G, for rolling horseshoeblanks, one provided with anannular groove and the other provided with creasers, said creasers beingplaced at right angles to the axis of the roll, the axes of the rollscrossing each other substantially as and for the pur- 'pose specified.

In'testimony whereof I, the said WILLIAM D. YOUNG, have hereunto set myhand.
